The answer is a. evade predators.
Animals that live in taiga had to adapt to seasonal changes, by changing their fur or feather color. For example, snow-show hare and ermine live in taiga and their fur color changes with environmental conditions. To effectively camouflage, their fur is white during the winter. That helps them blend into the snow. In the summer, where there is no snow, their fur is brown and similar to the soil color. This way<span> it is more difficult for their predators to spot them.</span>
C. ATP (Adenosine Triphosphate) has three phosphate groups attached. Each one of the groups occupies an extremely high energy bond (free energy that can do work). In muscle contraction, that high-energy bond is broken and the energy is released for muscle contraction. So when the bond is broken, you end up with ADP (Adenosine Dipohosphate) - broken down.
